Rhododendron microphyllum home care method

1. Prepare nutrient soil

Rhododendron microphyllum needs to be planted in suitable soil. You can use special orchid soil or choose high mountain humus soil, vermiculite, and perlite to prepare nutrient soil.

Rhododendron microphyllum prefers a warm environment and grows well in semi-shaded areas. In spring and autumn, it can be placed in direct sunlight in the morning and evening, while in hot summer, it should be moved to a cool and ventilated environment for cultivation. In cold winter, full-day sunlight care can be provided.

4. Temperature regulation

Temperature is an important condition for growing Rhododendron microphyllum. This plant can grow normally when the environmental temperature is between 12 and 25 degrees. However, in winter, it is important to keep warm, with the environmental temperature needing to be above 5 degrees. In hot summer, it is important to increase environmental ventilation, spray water on the leaves in a timely manner, and not exceed 35 degrees.

Points to consider in caring for Rhododendron microphyllum

The roots of Rhododendron microphyllum are very fragile and do not tolerate heavy fertilizers or fresh fertilizers, nor do they tolerate waterlogging. Attention should be paid to watering and fertilizing. It is best to dilute the fertilizer thoroughly with water or water immediately after fertilizing to reduce the occurrence of fertilizer damage.
